Electronic component

Abstract

An electronic component includes; a magnetic-body core having a plate-shaped portion and a core portion which extends from an upper surface of the plate-shaped portion; a winding wire which includes a wound portion wound by a rectangular wire into an Edgewise winding form and two non-wound portions extending from the wound portion to two distal ends, and the core portion is inserted through the wound portion; and a magnetic exterior body which covers at least the wound portion and the core portion. The two non-wound portions are respectively arranged along a bottom surface and at least one of the side surfaces of the plate-shaped portion. Parts of the two non-wound portions arranged along the bottom surface are electrodes.

What is claimed is: 
     
       1. An electronic component comprising:
 a magnetic-body core including a plate-shaped portion and a core portion, the core portion extending from an upper surface of the plate-shaped portion along a core extending direction, the plate-shaped portion having a plurality of side-surfaces and a bottom surface, the bottom surface being outwardly opposite to the upper surface, the plurality of side-surfaces including a first side-surface, a first cutoff side-surface, and a second side-surface, the first cutoff side-surface continuously extending from one end of the first side-surface, the first side-surface and the second side-surface being located opposite to each other with respect to the core portion in a plan view; 
 a winding wire which includes a wound portion wound by a rectangular wire into an Edgewise winding form and first and second non-wound portions extending from the wound portion toward the first cutoff side-surface of the plate-shaped portion and the second side-surface of the plate-shaped portion, respectively, the core portion being inserted through the wound portion; and 
 a magnetic exterior body which covers at least the wound portion and the core portion, 
 wherein a first part of the first non-wound portion extends from the wound portion along a first direction in the plan view, and the first part is located directly adjacent to the wound portion and faces the upper surface of the plate-shaped portion, 
 a second part of the second non-wound portion extends from the wound portion along a second direction in the plan view, and the second part is located directly adjacent to the wound portion and faces the upper surface of the plate-shaped portion, 
 an angle between the first direction and the second direction is approximately 90° in the plan view, 
 the first non-wound portion is arranged along the first cutoff side-surface, the bottom surface, and the second side-surface of the plate-shaped portion, 
 the second non-wound portion is arranged along the second side surface and the bottom surface of the plate-shaped portion, and 
 portions of the first and second non-wound portions that are parallelly arranged along the bottom surface of the plate-shaped portion are electrodes. 
 
     
     
       2. The electronic component according to  claim 1 ,
 wherein the plate-shaped portion and the core portion of the magnetic-body core are formed as separate bodies which are combined together to form the magnetic-body core. 
 
     
     
       3. The electronic component according to  claim 1 ,
 wherein the plurality of side-surfaces inlcude a second cutoff side-surface, and the second cutoff side-surface continuously extends from the other end of the first side-surface, and 
 the second non-wound portion is arranged along the second side-surface, the bottom surface, and the second cutoff side-surface of the plate-shaped portion. 
 
     
     
       4. The electronic component according to  claim 3 ,
 wherein ends of the first and second non-wound portions are positioned at opposite sides of the plate-shaped portion with respect to the core portion in the plan view. 
 
     
     
       5. The electronic component according to  claim 1 ,
 wherein the first non-wound portion is bent at an upper edge of the first cutoff side-surface of the plate-shaped portion, and a first ridge of a bent portion of the first non-wound portion extends along a third direction in the plan view, 
 the third direction crosses each of the first direction and the second direction in the plan view. 
 
     
     
       6. The electronic component according to  claim 1 ,
 an end of the first non-wound portion is positioned near the second side-surface of the plate-shaped portion, and 
 an end of the second non-wound portion is positioned near the second cutoff side-surface of the plate-shaped portion. 
 
     
     
       7. The electronic component according to  claim 1 ,
 wherein a distance along the core extending direction between the upper surface of the plate-shaped portion and the first part of the first non-wound portion adjacent to the wound portion is smaller than a distance along the core extending direction between the upper surface of the plate-shaped portion and the second part of the second non-wound portion adjacent to the wound portion.
